Exhaust Blues

have a set of genuine 750SS exhaust cans. Thought they would fit my bike (had high hopes!). It would appear the 2 into 1 system fitted is a home made job, and a pretty poor one at that. Phuck I say! Option would be to take the bike on a trailer to an exhaust shop and see if they can make it fit. The header bolts are rusty, they dont look real good which brings the issue of them snapping if I locate an exhaust sytem. Any ideas? Oh, added bonus, being a USA model the outer diameter headers fitted are 40mm (actually, they seem to be 38mm, my micrometer is not an expensive one..), im guessing the internal would be 35mm. I think this is unique to the USA. I could get an Aussie set but they are about 38mm internal.

If I had a choice I would def go for the bigger ones . I used to know a guy who ran a Ducati workshop and raced belt drive 2 valvers and he swore that the 1st thing to do was upsize the header dia and re-jet
Im understanding that the 2 into 1 is a bit naff . Do you have to fit some tested or certified exhaust to get the bike road legal or are you just looking to go back to original ?
Do you have a Mig welder ........its not that hard to make your own headers out of exhaust bends .
If the rusty studs you mention are the ones in the head it would pay to get them sorted before they break . Give them a good wire brush up and see just how rusty they really are . If none of the pitting is deeper than the bottom of the threads you may be ok ......but .....some peeps loose sleep over things like that.....not me :roll: :lol:

Hey Mc tool, yep the road worthy needs a standard pipe. They take photos of it and send it to Vicroads Also vicroads want to inspect it to see if it needs a specific engineering certificate for Victoria its been done in QLD but.... PITA really. I'll get the bike back together and take it and the standard exhaust to a exhaust shop, they will be able to make it fit. When I get a RWC and club plates Ill think about a 2 into 2. Have to get it made.
